Here is a great short documentary on Hans Zimmer‘s creative process for the Interstellar score. In it, Christopher Nolan explains how he hates to use temp scores and tries to get the score created early in the film’s production as it “has to be a fundamental ingredient, not a condiment to be sprinkled on the finished meal”.

Hans Zimmer also explains how the scoring process for this film was a very unusual one compared to most. He was only given a one page explanation about the basis of the film, and didn’t know the genre or anything else about it. He was then asked to create a track based on the main theme he’d been given and Nolan would use this for the film – the track was called “Day One” and is the main theme you hear in the film. An incredible score, and this is a very interesting short documentary that is well worth watching!
